i have recently acquired an older 16ga bolt action shotgun from a family friend. it is a western auto firearms revelation model 316B 16GA. i don't know much about the shotgun. have heard it was modeled after a mossburg 490 bolt action. have also been told it was manufactured by them? i know it was made aprox between 1966-1968 family friend bought it in 68. he has sense lost the bolt and i have been completely unable to find a used one as far as ebay and gunbroker. i have seen a few sites that have them for sale but aren't exactly credable. does anyone have any further information on this gun? and possibly may someone have a bolt laying around hat they would be willing to sell?
